Soy Quim Rodríguez
Llevo más de 25 años mejorando el aislamiento y la eficiencia de los hogares de mis clientes — y no te voy a engañar: cada vez que sale una nueva serie de perfilería, un nuevo vidrio, un aislante diferente o un sistema de instalación mejorado, todavía siento las mismas ganas de estudiarlo, de hablar con los especialistas y de probarlo con mis propias manos. Después de 25 años, eso no se ha apagado — se ha intensificado. Por el camino, he tenido la suerte de aprender sobre el terreno junto a profesionales brillantes, algunos de los cuales hoy ya son más amigos que colaboradores.
Tu reforma, tu casa nueva, tus ventanas — es tu gran proyecto. Yo estoy aquí para ayudarte a conseguir exactamente lo que tienes en mente, mejorarlo, evitarte errores y decisiones equivocadas. Toda mi experiencia y toda mi red de confianza a tu servicio para conseguir los mejores resultados.
